Hi, wondering if someone could help me diagnose a problem? My L2950 has been running very rough as of late. It starts OK and then after driving 50, or 100, or 250 feet then it will start to lose power and will sometimes stall. If I depress my clutch then I can keep the tractor from stalling. If it does stall, restarting is no problem. If I depress my clutch, then I have to wait 30 or so seconds for the rpm's to come back. Any ideas? (My fuel guage is reading over half full.)
